PROTOTYPE HISTORY

Beginning in early 2010, NS 6653 entered Juniata shop for 240 units planned through 2019. In August 2010, two SD60s (6567 and 6576) were retired and ear-marked for the SD60E program. Mechanically, the original prime mover, a 16-cylinder 710G3 model remained, but it was thoroughly rebuilt to 710G3B specs and rerated to 4,000 horsepower. The original shaft-driven air compressor was replaced with a new motor-driven compressor. All-new electrical cabinets and wiring, coupled with EMD’s EM2000 microprocessor controls, were installed, along with D99BTR traction motors. A new split-cooling system helps the SD60E meet Tier 0+ emissions requirements and reduce fuel consumption by an estimated 5 percent as compared to an older SD60 model. The SD60E’s tractive effort is rated at 109,000 pounds – unrebuilt SD60s are rated at 96,320-100,000 pounds.

Externally while most of the SD60’s carbody remained intact during the remanufacturing process, the program included installation of a completely new cab. Offering crews more protection – the original SD60 cab weighs 3,800 pounds versus 12,500 pounds for the new cab – as well as a spacious work environment, the cab – 59 square feet versus 74 square feet in the SD60E – was designed by NS with input from outside consultants and train crews. Fabricated by Curry Railroad Supply, a local vendor, it looks unlike anything else on U.S. rails with its pronounced numberboard/headlight housing and flat front with a centered cab door.

The first unit was finally released for service on November 15, 2010, carrying road number 6900. In March 2011, 6901 was released, followed by 6902 in June of that year. These three units gave NS mechanical personnel valuable feedback as the units toured the system, enduring “real life” testing.

In March 2012, the fourth SD60E emerged from Juniata as one of the 12 units initially funded for the program. But the pace of the remanufacturing process picked up as initial teething problems were addressed. The units soon met the carrier’s expectations and began entering revenue service on a regular basis.
